I am trying to find some ECC test vector for using. I just find some post (like this) and github resource (like this ) They are good reference to my C test code but I'd like to get some more advice...
Most of the test vector given looks like such format:
k (or m):m = 20 X = 0x83A01A9378395BAB9BCD6A0AD03CC56D56E6B19250465A94A234DC4C6B28DA9A Y = 0x76E49B6DE2F73234AE6A5EB9D612B75C9F2202BB6923F54FF8240AAA86F640B8
which by my understanding, k (or m) is the private key and (X，Y) are the public key--so (X,Y)=(m dot G), G is the base point defined by NIST or BP curve as “standard”. Q1：Is such understanding correct?
It is meaningful to see the X/Y are both 32Byte for curve sepc256k1--so expect the key length would be 256b(32byte);
my question is about the privite key (denote as m or k). for some test vector, m(or k) is given as:
m = AA5E28D6A97A2479A65527F7290311A3624D4CC0FA1578598EE3C2613BF99522
some other test vector m(or k), however, would be like below:
k = 112233445566778899 k = 10 k = 57896044618658097711785492504343953926418782139537452191302581570759080747168
These are all pure number, so Q2: Does that mean we need convert them to hex--and by doing that I can get exactly 32byte test vector?
